Indeed, this is helpful for me. I very much depend on controlled path
names, and I even use a class loader which is triggered by accessing a
proxy table. Using luac.lua, I was able to compile a GUI application
(which depends on about 20 Lua modules) into a single lua binary:

# luac.lua test.lua -L tek/ui.lua tek/ui/class/element.lua
tek/ui/class/group.lua tek/ui/class/area.lua tek/ui/class/family.lua
tek/ui/class/gadget.lua tek/ui/class/frame.lua tek/ui/class/window.lua
tek/ui/class/drawable.lua tek/ui/class/text.lua
tek/ui/class/display.lua tek/ui/class/application.lua
tek/ui/class/theme.lua tek/ui/class/drawhook.lua tek/class/object.lua
tek/class/list.lua tek/ui/class/border.lua tek/ui/border/default.lua
# rm $(find tek/ -name "*.lua")
# lua luac.out

... and it works. Thank you very much!
